Requirements

Caplin Trader 5 has the following requirements:

Node.js 18, including a build environment for native modules. See Installing Node.js.
Yarn package manager (latest version). See Installing Yarn.

There is a known issue in versions of npm later than 4 that prevents npm from working with Caplin Trader 5 projects.
Caplin CLI. See Installing Caplin CLI.
Internet access to the following public software repositories:
- The npm registry (https://registry.npmjs.org)
- GitHub (https://github.com)
If you access the Internet through a corporate proxy server that supports only NTLM authentication, then you need an intermediate proxy server to handle NTLM authentication on behalf of npm and Yarn. See Internet access and corporate proxy servers, below.

Neither npm nor Yarn provide built-in support for NTLM authentication to web proxies.

If you access the Internet via a corporate proxy that requires NTLM authentication, then possible solutions include:

Configure npm and Yarn to use an alternative proxy server, if one is available, that allows basic HTTP authentication for specific users and websites.
Configure npm and Yarn to use a local proxy (local to your development machine) that appends NTLM authentication headers before forwarding traffic to the main corporate proxy.

Contact your company’s IT support desk for a solution suitable for your network.
